# PACKAG ING AN D
CO NV E R TIN GA rela tively slow initial increase in viscosity is due to the e x othermi c reaction of the adhesive immedia t ely
after the mixin g process and the mechan ic al in fluences in the application system.
For short tria l runs the a dhe sive can be b a tch mixe d

. We recommend preparatio n of no more adhesive
than can be u s ed within 5-1 0 minu t es. A high speed s t irrer suitable for a homogen eous mixing should be used. However, the use of a me ter/mix/d i spense device which continuously mixes the ad hesive a t the chosen ratio, controls the feeding of the applicatio n unit, and stops production automatically in case of
machine failur e s, is indispe n sable for e x tended tr ials a nd normal pro duction.

When processing Mor-Free 403A + Coreactant, the safety rules for working with isocyana tes must be
observed. Th e adhesive co ntains mono meric MDI. See Material Safety Data Sh eet for specific details.

Cleaning The applicatio n unit should be cleaned before the adh esive bec omes insoluble by progressive curing, if th e machine stop s take more than 30 minu t es. Me thyle ne chloride c an be used to flush the mixing and metering units where a non-flammab l e solvent is req u ired. Consult the Ma terial Safe ty Da ta Sheet from the methylene chloride supplier for safe hand ling.

If the application unit and mixing de vice a r e combustion proof, they may be clean ed with esters or ketones
such as eth y l acetate and MEK.

Several commercially a v ailable solven ts are safe and effective for flushing and cleaning Mor-Free adhesive
residues from solven tless laminators an d meter / mi x/d i spensing equipment tha t do not ha ve combustio n proof ratings. We recommend contac ting e i ther Dynalo y , Inc

. ( 800-669-5709); www.dy naloy

. com ), o r Danko Industries (630-882-6070) for cleaning solve n t re commen dations. Always consult the solven t supplier’s MSDS for safe ty information be fore use.

Storage
Mor-Free 403A and its coreactants can be stored for 6 months in airtigh t, closed , original containers in dry rooms at temperatures of 7 0 ° ± 15 ° F

. O pened containers should b e used as qu ickly as possib l e.

Safety , Hand ling and Stor age
